The challenge description calls for playing the full game with one of each tower. It does not specify whether “once” means once per stage or once across the entire run, so confirm the rule you’re following before placing a duplicate.
To attempt the challenge, track which tower types you’ve placed and avoid using a type again under your chosen interpretation of the limit. The supplied description gives no tower-placement strategy or other gameplay requirements.

The explanation is clear, especially for beginners.
Nice guide. I am checking the other Kingdom Rush 5: Alliance TD+ articles next.
This saved me time in the early game.
I tried this today and it worked better than my old setup.
